Universal energy-dependent pseudopotential for the two-body problem of confined ultracold atoms
Physical Review Research, 2022 The two-body scattering amplitude and energy spectrum of confined ultracold atoms are of fundamental importance for both theoretical and experimental studies of ultracold-atom physics.

Atomic-Scale Confinement of Resonant Optical Fields [PDF]
Nano Letters, 2012 In the presence of matter, there is no fundamental limit preventing confinement of visible light even down to atomic scales. Achieving such confinement and the corresponding resonant intensity enhancement inevitably requires simultaneous control over atomic-scale details of material structures and over the optical modes that such structures support.

Prospects for single-photon sideband cooling of optically trapped neutral atoms
Physical Review Research, 2021 We propose a cooling scheme for realizing single-photon sideband cooling on particles trapped in a state-dependent optical potential. We develop a master rate equation from an ab initio model and find that in experimentally feasible conditions it is ...

Toy model of harmonic and sum frequency generation in 2D dielectric nanostructures
Scientific Reports, 2021 Optical nonlinearities of matter are often associated with the response of individual atoms. Here, using a toy oscillator model, we show that in the confined geometry of a two-dimensional dielectric nanoparticle a collective nonlinear response of the ...

Coherent interaction of atoms with a beam of light confined in a light cage
Light: Science & Applications, 2021 Light-matter interaction in the hollow-core light cage, at the example of EIT in alkali atoms in this work, presents a novel approach to implement integrated on-chip devices for applications in quantum optics and quantum information.

Spatial confinement of muonium atoms [PDF]
Physical Review A, 2016 We report the achievement of spatial confinement of muonium atoms (the bound state of a positive muon and an electron). Muonium emitted into vacuum from mesoporous silica reflects between two SiO$_2$ confining surfaces separated by 1 mm. From the data, one can extract that the reflection probability on the confining surfaces kept at 100 K is about 90 ...

Emergent s-Wave Interactions between Identical Fermions in Quasi-One-Dimensional Geometries
Physical Review X, 2023 Orbital degrees of freedom play an essential role in metals, semiconductors, and strongly confined electronic systems. Experiments with ultracold atoms have used highly anisotropic confinement to explore low-dimensional physics, but they typically ...

Confining and compressing the atom [PDF]
The European Physical Journal D, 2020 Abstract A review of effects due to the confinement and compression of atoms is presented. It is argued that they provide new insights into the properties of atoms and, in particular, into their interactions with the microscopic environment.
